So i thought i needed a capture card to be able to stream my Wii U game play. Not really wanting to shell out for a card it dawned on me that my GTX 9600 might already have the capability, and is actually a capture card anyway without me knowing? On the card i have the standard HDMI port, a DVI port and 3 Display Ports. Now if i was to buy a HDMI to Display Port converter for a couple of £ off e-bay would this mean i could plug in my Wii U through the converter to my graphics card and pick up the game play this way? I'm not 100% computer savvy but i know enough to think this would work in theory, or am i just being cheap? and shoudl just buy a capture card which is actually built for this.

New to speed running, looking at running one of my favorite all time games HOMM (heroes of might and magic) over on my twitch channel. So n00b question i see a lot of runners using timers, with splits. Where can i find one to use for myself, which is easy to set up and use?

So i'm thinking of buying a Pi Retro System ( https://www.piretrogaming.com/ ) would i be able to run speed runs on this? As its basically a stand alone EMU system.
